iBCS2 emulator core files.
This is the main files for the iBCS2 emulator. It can be use compiled into the kernel by using: options IBCS2 options COMPAT_IBCS2 or as a lkm module using: options COMPAT_IBCS2 and then loading it via the ibcs2 script in /usr/bin REMEMBER: this code is still experimental ! NO WARRENTY ! Submitted by: sef@kithrup.com, mostyn@mrl.com, sos@kmd-ac.dk
